A cell is the most basic unit of life, for any tree or animal. The cell membrane is the outer cover of the cell, and it controls the movement of materials into and out of the body cell. The cell layer is semi-porous with the goal that charged particles could not diffuse down or up a concentration cell into or out of the cell. There are cell-bound proteins that vehicle charged particles like K+, Na+ and Ca2+ over the cell film and the net impact is that the cell is adversely charged (about – 70 mV) regarding the extracellular space (Polo et al., 2010).
The reason why a cell has different electrical charge also known as Voltage across its membranes is a result of the activities of the electrogenic pump. The voltage gradient is created when electrons are moving across a cell membrane. During such event, the side of the membrane from which the electrons are moving away becomes positively charged. The other side of the membrane towards which the electrons are moving becomes negatively charged. For example, Sodium is an ion which is positively charged, making it impossible for sodium ion to diffuse across the cell membrane. Therefore, such diffusion takes place through an active transport in which protein pumps in the cells pump Na+ across the membranes. This process consumes the energy (ATP energy) made through respiration (Polo et al., 2010).
The movements of ions or any other material across the cell membranes are enabled by the proteins molecules that are found in the cell membrane.

There are carrier and channel proteins which are responsible for carrying molecules and ions respectively.
The most basic knowledge to note about body cells, it is that they transport materials in the body from a region of high concentration to that of low concentration.
